From: Cortland Tölva <cst@tolva.net>
Userspace submits a USB Request Buffer to the kernel, optionally
discards it, and finally reaps the URB. Thunk buffers from target
to host and back.
Tested by running an i386 scanner driver on ARMv7 and by running
the PowerPC lsusb utility on x86_64. The discardurb ioctl is
not exercised in these tests.
